The interest earned in the Lifelong Income Fund matters, and it matters A LOT, because the interest earned is calculated into your monthly payout. If the LIF does not earn any interest, your monthly payout will be much lower.
It's completely false and misleading to claim that the interest in the LIF does nothing for you, because you definitely get the benefits out of the interest earned.
ok I am attending a CPF talk later, so now got little bit of time, I quickly do this writeup:
Dork32 is talking about if he choose Basic Plan, effectively he only earns 3.2% on his RA balance at 65, the maths as follows, simplified just for calculation exercise purpose:
Balance in RA at 65 =200k
CPF Life Premium =20% = 40k
Balance in RA after premium = 160k
RA 4% interest on 140.8k = 6400
Effective interest on RA balance of 200k = 6400/(160k+40K) = 3.2%
Although CPF Life Premium earns 4% interest, it gets paid into the CPF Life pool. Under Basic Plan, mthy payouts starts from RA until 90, then payouts come from CPF Life pool.
If dork32 thinks he will not survive past 90, then he will never get to enjoy the 4% interest paid in the CPF Life pool. It is as good as zero, ie he write-off that 4% interest, treat it as bad debt in accounting 101. But his capital or premium of 40k he will be able to get back. That's how he derive the effective interest of 3.2% on his capital of 200k, as calculated above.
It is not incorrect, false or misleading for his own accounting treatment of his assets. Should he survive after 90-93, he will be getting CPF Life mthly payouts from the pool which includes the 4% interest accumulated there for 25+ years. Then he can start accounting for it as his “recovery of bad debt” or “profit” if he survives longer.
Remember, the 40k premium sits in the CPF Life pool for 25 years (from 65 to 90 if he starts at 65), if he die before 90, he loss all 4%*40k compounded over 25 years!
So we are only talking about Basic Plan, if we die before 90.
